Paytm Mobile Solutions — flight ticket refund issue with paytm

Address:

Thane, Maharashtra, 421301

We booked total of 5 indigo flight tickets for to and fro journey from mumbai to kochi with paytm on the date of 17th aug 2019.
Paytm booking id for first three tickets is [protected]
And paytm booking id for remaining two tickets is [protected]
As you are aware flight to kochi were canceled on 9th aug 2019 due to heavy downpour and flood like situation.
It has been more than 7 days and we still have not received refund for paytm booking id [protected], even though indigo has communicated to us that they have already issued guidelines for refund to ticketing agency.
We have received refund for our booking id [protected] on the same day even though tickets were booked afterwards.
Even after communicating with paytm customer support team we are just getting repetitive and non convincing answers.
We are really feeling frustrated and helpless in this situation.
